摘要翻译:
本文分析了新冠肺炎疫情对92个国家人口和股票市场的影响。我们将逐国股票市场动态与累计新冠肺炎病例和死亡人数以及新病例轨迹进行比较。首先,我们检验了累积病例和死亡的多变量时间序列,特别是关于它们随时间变化的结构。我们揭示了病例和死亡时间序列之间的相似性,以及时间序列结构发生变化的关键日期。接下来,我们对新病例时间序列进行分类,展示了五类特征轨迹,并根据疾病波的行为量化了它们之间的差异。最后,我们发现一个国家的股票市场表现与他们管理COVID-19的成功没有关系。每个国家的股票指数都对这一流行病的国内或全球状况没有反应。相反,这些指数一直高度统一,大部分变动发生在3月份。

英文摘要:
This paper analyzes the impact of COVID-19 on the populations and equity markets of 92 countries. We compare country-by-country equity market dynamics to cumulative COVID-19 case and death counts and new case trajectories. First, we examine the multivariate time series of cumulative cases and deaths, particularly regarding their changing structure over time. We reveal similarities between the case and death time series, and key dates that the structure of the time series changed. Next, we classify new case time series, demonstrate five characteristic classes of trajectories, and quantify discrepancy between them with respect to the behavior of waves of the disease. Finally, we show there is no relationship between countries' equity market performance and their success in managing COVID-19. Each country's equity index has been unresponsive to the domestic or global state of the pandemic. Instead, these indices have been highly uniform, with most movement in March.
